I claim:

In combination7 a head member adapted to be rigidly mounted upon an electric motor, a hub fixedly mounted in the head in axial relation thereto and provided With `a cylindrical bore adapted to engage a spindle, a. spindle adapted to support the motor rotor seated in the bore, a nut threaded upon the spindle to hear against the hub, the said hub'being separated longitudinally and provided with means for drawing the separated parts together whereby to rigidly Clamp the spindle in the hub.
